. J. SCHIFTNER RAILWAY GRADE CROSSING GATE Filed Jan 7, 1925 Application filed have?" 7, 19%. Serial No.

To all whom it may concern;

Be it known that I, JOSEPH Scnim'imn, a citizen of the United States, residing at 111 Glovizo in the Province of Cemogoey, Coho have invenled certain new and useful Improvements in e, Reilway-Gi*ede-(h'0ssing (J2me of which the following is e soecifi cetion.

This invention relates lo gates for railway grade crossings end has vfor its primary object the provision of such e gate that moved to end closed position in en enlirely automatic manner and Withoui; 1",- ouiiing the etleneion of e, gatemen.

A further chime of the invention is he rovide do gel/c for milwey grade croesingo whei'cinlhe some is mounted for vertical swinging movement upon the horizontal pivot andwherein the neture of the same is to assume at all times a closed position, means heing pmvided for normally maintaining the gate in an open position and means being provided at remote pcinrec from opposite sides of the grade crossings opemhic hv ihe train passing over lihe tracks release the gait-c from iie e position whereby i-he some will mztcmeliceliy drop to a closed position.

' ll furl-her object of ihe invention is to pro vide meme the grade crossing operable hy the movement of the car over the h'ecksic throw the some to open position.

A. furihei' and impoi'hmt clojeci ho pro vide a, device of this cheiiacier izhet is of relatively cheep and simple construction and wherein there is lillzle liehilihy of the wol'lo ing'per'be becoming out' of orde'srand wherein the same will operate efiiciemzly under ell conditions.

With the foregoing and other ohjccts in view as fiche nature of the invehlion will he hotter understood, the some comprises the characters throughout the several views:

My invention per se ccnsititules the provision of a vertically disposed standard "4 located at one side of the highway 6 end who which is pivotally secured h y a, horizontal pivot 8 a gate 9 of the her or pole type, it being noted that the pivotal connection is adjacent one end of the gale in order that fiche tendency of vthe some is lo normally maintain 3- closed position disclosed by the dotted limes in Figure l.

latch bolt to the position shown in Figures 1 and 2 and by the engagment of the latch bolt with said armature the gate will be maintained in open position.

At point-s remote from opposite sides of the highway 6 are electrical switch nechanisms designated respectively A and 13. Each of these switch mechanisms comprises a. metallic casing. within which is a stationary contact 21 and a sliding contact 22. The sliding contact is carried by a rod 23 that projects outwardly of the casing amt which is pivotaly connected at its forward end as at at to the lower end of a vertical rock bar -carried by a suitable frame 26 disposed adjacent the outer side of one of the rails of the track way. 5. This rock bar 25 is maintained in normal vertical position through the medium of a. pair of coil springs 2727 that are secured at their opposite ends respectively to the rock bar and to the ftrame 26.

The stationary contact 21 of the switch mechanisms are electrically connected to certain poles of storage batteries C and C. The other poles of these batteries being electrically connected as at a and a to one contact of the electro-magnet 17,the other contact of this electro-magnet being electrically connected to the sliding contact 22-22 of the, switch mechanism through the medium of wires Z) and-b.

Theupper ends of the rock bars 25 25 project slightly above the tread of the adjacent rail engaged by the wheels of the train passing over the highway. It being obvious that the train moving in either direction will engage one of the rock bars for completing the circuit between the storage battery and electro-magnet 17 whereupon the armature will be retracted and when disengaged from the latch bolt 13 the gate 9 will swing downwardly to closed position under its own weight.

At the opposite side of the highway 6 from the standard 7 is a vertically disposed hollow post 24 through which is slidable a 1od25 that projects through the upper end of the post and upon which is adapted to rest the 'gate 9. The lower end of this member 25 engages upon one end of a transversely arranged rock bar 26 that is pivoted at 27 to a casing 28 disposed along the outer side of the adjacent rail of the track way as clearly shown in Figure? Disposed for vertical sliding movement within the casing 28 is a pin 29 that extends upwardly above the tread of the rail to be engaged by the wheels of the car passing over the track way. The lower end of this pin rests upon the adjacent end of the rock bar 26 and it will be obvious that as the wheels of the car engage said pin the rock bar 26 will be actuated for forcing upwardly the member 25 and due to the quick action of the same the gate 9 will be thrown to open position and will be maintained in open position through the medium of the latch mechanism hereinbefore described.

The foregoing description. when considered in conjunction with the accompanying drawing, it will be apparent that I have provided a highly novel and efficient railway grade crossing gate that will be moved to open and closed position in an entirely automatic manner.

Minor changes. may be made in the invention without departing from the spirit of the invention and scope of the appended 0 arms.

Having thus described the invention, what I claim is 1. A grade crossing gate mechanism of the character described including a swiging gate at one side of the crossing, pivoted so as to tend to move to a closed position because of its own weight, means for maintaining the gate'in an open position, a post on the other side of the crossing against which the end of the gate is adapted to rest when closed, a rod movable longitudrally through the post for engaging the gate and means for pushing upwardly on the rod for. projecting the gate to an open position, said means being actuata-ble by a spring.

2. In combination, a pivotally mounted gate fulcrumed so as to normally close under its own weight, a post for receiving the gate in its closed position, a rod slidable through the post, a lever pivoted so as to provide a long and a short arm, the long arm having its end engaged with the lower end of the rod, and a slidably mounted pin for engaging the short arm so that a frame wheel may engage said pin for swinging the levei, thus pushing the rods and projecting the gate to an O)6I1 position.

In testimony whereoi I aflix my signature.
